Capture SIGKILL/SIGTERM to terminate the process gently with SignalCondition #218

Looks like Julia will have (maybe already from v1.14?) a way to handle signals. I think it'd be great for us to use this to terminate the tests nicely, reporting the failure and the error messages, when the processes receives a SIGKILL/SIGTERM, for example when the CI job is cancelled: at the moment the process terminates abruptly, and the logs and error messages are lost into the void.
